VENTILATOR.

Specification of Letters Patent.

Patented March 6, 1906.

Application lied February 3, 1905. Serial No. 244,000.

To alii whom t may concern.-

Beit known that I, WILLIAM TALBOT Cor- TIER a citizen of the United States7 residing at Chicago, in the count of Cook and State of Illinois, have invente new and useful Imrovements in Ventilatore, of which the foiowing is a s ecification.

My invention ertains to ventilators; and it contemplates t e rovision of a ventilator whichl is highly e cient in exhausting a building or a artinent of vitiated or foul air and is also simple and inexpensive in construction and well adapted to withstand eX- posure to the weather.

The invention will be fully understood from the following description and claims when taken in connection with the accomp anying drawings, forming part of this speciiication, in which Figure 1 is a side elevation of the ventilator constituting the preferred embodiment oi' my invention. Fi 2 is a vertical central section of the ventilator with the lower portion of one side wall of the uptake broken away, and Fig. 3 is a horizontal section taken in the plane indicated by the line 3 3 of Fig. 2 lookin downwardly.

Simar letters designate corresponding arts in all of the views of the drawings, reei'rilig to which- A is the lower portion of the uptake of my novel ventilator, and B is the upper comparatively large portion of said uptake. At this point I desire to state that all oi my nove ventilator exceptin the 'inductors,

resently described, is pre erably of wood.

he lower portion A comprises a base a, designed to rest on and communicate with the interior of the building or apartment to be ventilated, upright corner-posts b, and boards c, arranged at the outer sides of and connected to the corner-posts, the boards c being also interposed between the base a and the corner-posts and connected to both, Fig. 2. The upper comparatively large portion B is made up of u right corner-posts d and boards e, both pre erably of wood, and it is provided with iateral openin s f at its up er end, a cap g, secured over an pro'tecting aterally beyond saidv end, brackets disposed the cap g and connected to the boards an corner-posts, and ribs 7c lc 7c, connected together and to the boards e and arranged immediately below the brackets so as to assist in supporting said brackets D D are inductors, preferably of galvanized iron. The inductors per se may be of any suitable t Tpe without iiivoiving a de parture from tie scope of my invention. I prefer, however, in order to increase the ef" ciency of the inductors to gradually reduce the saine in size from their iower receiving ends to their discharge ends and to arrange and secure said discharge ends between the upper end of the board covering c of portion A and the lower end of the board covering e of portion B, Fig. 2. The spaces between the sides of the inductors D and the cornerosts d are closed b f blocks, (shown in plan in Fig. 3 and lettere C,) this in order to prevent air from entering the uptake except through the said inductors D.

The lower portion A and upper portion B ci the uptake are preferably connected together and iixed with rcs )ect to each other through the medium of tlie inductors D, to which their boards are bolted, as shown.

' In the practical operation of my novel ventilator it will be observed that the atmospheric air passing upwardly through the inductors will create a strong suction in the upper portion B of the uptake and th at the said suction will operate to eiectually exhaust an apartnient or building of vitiated or foul air. It will alsobe observed that the suction created in the upper portion of the uptake is increased in force bythe size of saidu per portionin crosssection as compared wit the lower portion.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a ventilator, the combination with an uptake comprising a lower portion, and an upper portion, comparatively large iii crosssection, arranged with its lower end flush with the upper end of the lower portion, whereby verticaily disposed o enings are formed between the said ends of t e portions; of induotors arranged outside the uptake and having their discharge ends secured in the openings between the adjacent ends of the lower and upper portions.

2. In a ventilator, the combination of a lower uptake portion comprising cornerposts and a covering arranged on and connected to said posts, an upper uptake portion, comparatively large in cross-section, comprising corner-posts and a covering arranged on and connected to said cornerposts; the lower end of the covering of the upper portion being flush with the upper end IOO of the covering of the lower portion, whereby vertically-disposed openings are afforded between the said ends of the portions, and inductors arran ed outside the uptake and having their disc arge ends secured in the said openings of the uptake.

3. In a ventilator, the combination of a lower uptake portion comprising cornerposts and a covering arranged onV and connected to said posts, an upper uptake portion, comparatively large in cross-section, comprising corner-posts and a covering arranged on and connected to said cornerposts; the lower end of the covering of the upper portion being Hush with the upper end of' the covering of the lower portion, whereby vertically-dis osed openings are afforded between thesai ends of the portions, inductors arran ed outside the uptake and having their ings of the uptake, and means closing the spaces between the sides of the induotors and t e adjacent corner-posts.

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- 2 5 nesses.
